"I had to stop taking Savella when titrating to 100 mg daily because my normally low normal blood pressure skyrocketed. Just prior to that it caused blurred vision and migraines. I reported the side effects to the FDA. I have a long history of fibromyalgia, 16 spinal disc bulges and herniations, polyarthralgias, arthritis and severe myofascial syndrome. Now, several months later I am willing to try another trial because the Savella is the only thing that helped me.  I bought a blood pressure cuff and will monitor my pressure daily and will not go beyond 50 - 75 mg/day if I get relief. Hopeful."
